Friction is cut down in a hovercraft by the large volume of air that blows out from under the skirt, making the skirt rise above the ground. In essence, the hovercraft is floating on a bubble of air, and has very little friction with respect to the ground.

Why is friction cut down in a hovercraft?
How is friction cut down in a hovercraft? This is done by hovering over the surface Why is friction cut down in a hovercraft? Because the surface of the hovercraft is smooth
How does a balloon hovercraft work does it have lots of forces acting on it and what does friction have to do with it?
It has lift by having hot air, which rises. Gravity, Lift, and Friction act upon the balloon hovercraft. The friction is a fluid friction known as Air Resistance.
How does the flow of air reduce friction of the hovercraft in motion?
How does the flow of air reduce friction of the hovercraft in motion?
What is the purpose of making a hovercraft?
The purpose of making a hovercraft is to reduce the friction and drag that boats experience on the water. This makes the craft faster, more efficient, and more fun!
How and why friction is cut down in a car engine?
How - with cooling oil Why - because friction causes heat, and overheating is bad for moving parts.
What are the Small balls that help cut down on friction inside machines?
Ball bearings
How can a hovercraft go?
a hovercraft can go upto 60 mph
Why is friction cut down on a dance floor?
Friction on a dancefloor is reduced by the highly polished floor and leather bottomed shoes worn by the dancers
Why do things go faster underwater then on the surface?
Because a hovercraft rides on a cushion of air, there is less contact between a hovercraft and water, so there's less friction to slow it down as compared to a regular watercraft.
What is used to cut down friction in a car engine?
How- cooling oil why- overheating is bad for the engine parts
What is friction between moving parts of an engine?
Friction is cut down in a car engine for two very important reasons. First, cutting down friction increases horsepower. It takes horsepower to overcome friction; so anything that can be done to cut down friction will increase the horsepower. Second, friction causes heat to be produced. Too much heat is bad, because if the engine gets too hot, then metal is softened and weakened, leading to failure of engine parts. The engine has a cooling system to remove unwanted heat, but too much friction would require a larger and more efficient cooling system to remove the excess heat, which would add expense and weight to the car. Motor oil is used to cut down the friction in the car engine. Also, very close tolerances in production of engine parts helps to cut down friction.
Why is friction an important factor to consider when designing a race car?
Gravity is good. It keeps the cars down on the track, and the fans in their seats. Friction is bad. If there was no friction, then you could cut your engine when you hit 200 and just keep going. But friction robs your kinetic energy, so if you back off your engine, then your car slows down.
